Data Visualization Using Hardware Accelerated Spline Interpolation
نویسندگان
چکیده
We present our method of real-time rendering of grid-structured data. The method uses bicubic spline interpolation running on common current graphics hardware to map the values to a texture. It allows us to render isolines of the visualized data and dynamically change the visualization parameters. We have implemented the method and incorporated it into a system of real-time simulation and visualization of combustion processes in pulverized coal boilers. We have compared the visual quality of produced images with the previously used visualization methods.

Prefiltered B-Spline Reconstruction for Hardware-Accelerated Rendering of Optimally Sampled Volumetric Data
In this paper odd-order B-spline filters are proposed to reconstruct volumetric data sampled on an optimal Body-Centered Cubic (BCC) grid. To make these filters nearly interpolating, we adapt a previously published framework, which is based on a discrete frequency-domain prefiltering. It is shown that a BCC-sampled B-spline kernel is not invertible, therefore the interpolation constraint cannot...
متن کاملGeometric Continuity Two-Rational Cubic Spline with Tension Parameters
Abstract— A smooth curve interpolation is very significant in computer graphics or in data visualization. In the present paper -piecewise rational cubic spline function with tension parameter is considered which produces a monotonic interplant to a given monotonic data set. The parameters in the description of the spline curve can be used to modify the shape of the curve, locally and globally. ...
متن کاملIntegrated Registration and Visualization of Medical Image Data
Different imaging modalities give insight to vascular, anatomical and functional information which assist diagnosis and therapy planning in medicine. Registration and consecutive visualization allow to combine the image data and thereby convey more meaningful images to the clinician. Applying a voxel based approach based on mutual information, accurate and retrospective registration is provided...
متن کاملMonotone Rational Trigonometric Interpolation
This study is concerned with the visualization of monotone data using a piecewise C rational trigonometric interpolating scheme. Four positive shape parameters are incorporated in the structure of rational trigonometric spline. Conditions on two of these parameters are derived to attain the monotonicity of monotone data and other two are left free. Figures are used widely to exhibit that the pr...
متن کاملHigh-Quality Interactive Volume Rendering on Standard PC Graphics Hardware
We propose an interactive volume rendering method using flexible texture mapping capability of standard PC graphics hardware. Although volume rendering is computationally expensive, interactive visualization can be achieved by slice-based method in which volume data set is represented as a stack of polygonal slices and rendered by texture mapping and α-blending function accelerated by graphics ...
